Can You Add Shockpads To Existing Artificial Grass?

If you already have artificial grass installed, you may be wondering whether it is possible to improve the surface without starting again from scratch. That often comes up after homeowners discover shockpads.

Perhaps the lawn feels harder underfoot than expected. Maybe children are using the garden more than originally planned. In some cases, families install artificial grass for appearance, then later decide they want a softer, more forgiving surface for play, pets or everyday use.

That naturally leads to one question: Can you add shockpads beneath existing artificial grass?

In many cases, yes, but it depends heavily on how the original lawn was installed, the condition of the grass and whether the existing base is suitable for reuse.

That last point matters most.

Retrofitting a shockpad is rarely as simple as sliding an underlay beneath the surface. It often involves lifting the existing grass, assessing the base and deciding whether the current installation is strong enough to support the upgrade.

For some gardens, retrofitting makes excellent sense. For others, replacing part or all of the installation may be the more practical option.

The goal is not simply to ask whether shockpads can be added. It is to decide whether adding one is actually worthwhile for your specific garden.

What Is A Shockpad And Why Would You Add One Later?

A shockpad is a cushioning layer installed beneath artificial grass to improve comfort, support and overall surface performance.

It sits between the grass and the prepared base, acting as an additional layer that helps manage how pressure moves through the installation.

If you are unfamiliar with the product, our guide to what are artificial grass shockpads covers the basics in more detail.

Most homeowners do not install shockpads because they simply do not know about them when their lawn is first laid. Others deliberately skip them to reduce upfront costs.

It is usually later, once the lawn is being used in real life, that the value becomes clearer.

Common reasons people consider adding a shockpad after installation include:

• the lawn feels firmer than expected

• children are using the garden more often

• the surface is being used for active play

• pets repeatedly use the same routes

• homeowners want a softer, more comfortable feel

A family garden is a good example.

A couple may install artificial grass mainly to reduce mowing and maintenance. Two years later, their children are using the garden daily for football, rough play and climbing equipment. Suddenly, comfort and cushioning become much more important than they were during the original installation.

That is often when retrofitting enters the conversation.

Can Shockpads Be Added Beneath Existing Artificial Grass?

In many situations, shockpads can be added beneath existing artificial grass, although feasibility depends on the condition of the lawn and how it was originally installed.

This is the honest answer.

There is no universal yes or no.

Whether a retrofit is realistic depends on three main factors:

1. The Condition Of The Existing Grass

The first question is whether the grass itself is worth lifting and relaying.

Older lawns may already show:

• flattened fibres

• seam separation

• stretched backing

• lifting edges

• worn high-traffic zones

If the grass is heavily worn, lifting it to add a shockpad may not be worthwhile.

For example, if a lawn is seven to ten years old and already losing resilience, the labour involved in retrofitting may make a full replacement more sensible.

2. How The Lawn Was Originally Installed

Installation method matters enormously.

Grass that was professionally installed with good joins, stable edging and a strong base is usually a better retrofit candidate than DIY installations with inconsistent groundwork.

Certain installations are easier to lift cleanly than others.

Adhesive-heavy seam joins, aggressive fixing methods or damaged perimeter edging can all make removal more difficult.

3. The Condition Of The Sub-Base

The sub-base often determines whether retrofitting makes sense.

Even if the grass looks fine, problems underneath may change the recommendation entirely.

If the base has:

• poor compaction

• soft spots

• drainage problems

• settlement

• uneven levels

simply adding a shockpad will not solve the real issue.

That is why many retrofit projects begin with base assessment rather than product selection.

When Retrofitting A Shockpad Makes Sense

Not every artificial lawn benefits equally from a shockpad retrofit.

The key question is simple:

Would the added comfort and support noticeably improve how the lawn is used?

In some gardens, the answer is clearly yes.

Family Gardens With Heavy Daily Use

Busy family gardens are among the strongest candidates.

Artificial grass in these spaces often sees constant activity, including:

• football

• games

• outdoor play

• social gatherings

• daily foot traffic

That repeated use creates predictable wear patterns.

The strip outside patio or bifold doors is a classic example. Even on large lawns, most traffic funnels through a narrow section near the house.

Over time, these concentrated routes experience greater surface stress.

A shockpad may help reduce how harshly that pressure transfers through the installation.

Children’s Play Spaces

Shockpads become more attractive when the lawn functions as an active play area.

Slides, swings, climbing frames and trampolines all create repeated impact in concentrated zones.

That type of use places greater stress on both the grass and the layers beneath it.

For parents, the decision often comes down to comfort as much as performance.

Pet-Friendly Gardens

Dogs create surprisingly consistent wear routes.

Many repeatedly patrol fence lines, sprint toward gates or run the same chasing routes across the lawn.

Sharp turns and repeated acceleration create concentrated strain.

In these gardens, a shockpad may help improve overall surface feel while supporting better load distribution in high-use areas.

Lawns That Feel Too Hard

Sometimes the issue is simply comfort.

A lawn may look excellent but feel firmer than expected.

This is especially common when artificial grass has been installed over a very compact base without cushioning.

In these cases, retrofitting may be worth considering even when the lawn is otherwise performing well.

What Happens During A Shockpad Retrofit?

Retrofitting a shockpad usually involves much more than simply adding a layer beneath the grass.

The process typically includes four stages.

Stage One: Assess The Existing Installation

Before anything is lifted, the existing lawn needs assessment.

This involves checking:

• grass condition

• seam integrity

• edge fixing

• drainage performance

• base stability

This stage determines whether reuse is realistic.

Stage Two: Lift The Existing Grass

If the lawn is suitable, the grass is carefully lifted.

This sounds straightforward but can be one of the trickiest stages.

Older joins may separate during removal. Adhesive can resist clean lifting. Edge fixings may need replacement.

The older the lawn, the more careful this process usually becomes.

Stage Three: Install The Shockpad

Once the base is exposed, the shockpad is laid and positioned.

This stage requires clean joins and consistent placement to avoid uneven support beneath the grass.

Poor positioning can create visible inconsistencies later.

Stage Four: Relay The Grass

The existing lawn is then refitted.

This includes:

• rejoining seams

• securing edges

• brushing fibres

• checking finish levels

Done properly, the lawn should sit evenly over the new underlay.

Can Your Existing Artificial Grass Be Reused?

This is often the biggest question for homeowners. The honest answer is: sometimes. Whether reuse is possible depends on age, wear and installation quality.

When Reuse Is Usually Possible

Reuse is more realistic when the grass is:

• relatively new

• structurally sound

• free from major seam damage

• still holding fibre resilience

• properly installed originally

A well-maintained lawn that is only a few years old often has strong reuse potential.

When Replacement May Be Smarter

Sometimes reuse creates false economy. If the grass already shows heavy wear, retrofitting may simply delay inevitable replacement.

In those cases, upgrading both the grass and shockpad together often makes more practical sense.

This is especially true where fibres are heavily flattened or backing is deteriorating.

Common Retrofit Challenges Homeowners Should Know About

Retrofitting can deliver worthwhile results, but it is important to understand the limitations.

This is not always a simple upgrade.

Drainage Problems

One of the biggest misconceptions is that shockpads automatically improve drainage. They do not.

Drainage depends mainly on the sub-base, fall and overall installation design. A porous shockpad can support water movement, but it cannot fix poor groundwork.

For more context, see our guide on why you need shockpads under artificial grass.

Hidden Sub-Base Problems

Some issues only become visible once the lawn is lifted.

Common discoveries include:

• soft spots

• settlement

• poor compaction

• weak edging

These issues can increase project scope.

Reinstallation Challenges

Lifting and relaying existing grass introduces risk. Older grass can stretch, crease or lose seam integrity during reinstallation. That risk increases with age. This is why retrofitting is not always the cheapest route.

Are Shockpads Worth Adding?

Whether a retrofit is worthwhile comes down to value rather than simple cost.

The right question is not: “How much does a shockpad cost?”

It is: “Will this meaningfully improve how my garden is used?”

For many homeowners, the answer depends on lifestyle. A lightly used decorative lawn may gain little from retrofitting. A busy family garden used daily by children or pets may benefit much more.

Shockpads can potentially improve:

• comfort underfoot

• cushioning

• surface support

• high-traffic usability

What they cannot guarantee is equally important.

They do not guarantee:

• longer grass lifespan

• improved drainage

• maintenance-free performance

• universal safety

Understanding both sides helps buyers make better decisions.

Frequently Asked Questions About Retrofitting Shockpads

Can shockpads be added to existing artificial grass?

Yes, in many cases, although feasibility depends on grass condition and installation quality.

Do I need to replace my artificial grass?

Not always. If the grass is still in good condition, reuse may be possible.

Are shockpads worth adding?

They can be worthwhile where comfort or heavy usage makes cushioning more valuable.

Will a shockpad affect drainage?

It may complement drainage, but it will not solve underlying drainage problems.

Can pets use artificial grass with shockpads?

Yes, provided the wider grass system is suitable for pet use.

Adding shockpads beneath existing artificial grass is often possible, but it is not always the right solution.

The success of a retrofit depends on three things above all else:

• the condition of your current grass

• the quality of the original installation

• how the garden is actually used

For some homeowners, retrofitting offers a practical way to improve comfort and usability without replacing the entire lawn.

For others, especially where the grass or base is already deteriorating, replacement may be the smarter long-term investment.

The best next step is assessment.
